Well, it runs and does… something. I haven't yet figured out what's going on. WASD does nothing. It's like i'm in the very bottom of a pit and can't move. I can't tell which way is up, and pointing and WASDing in any direction doesn't change anything.

Edit: I quit it and restarted and now I can tell that I fell onto a surface, and I initially was able to control moving a tiny bit, but then nothing. There's some kind of force preventing me from moving. Maybe it's the black snow pummeling me in the face?

Take 3: okay, if you brake while falling, then you can WASD over to somewhere else while you fall, but it seems that as soon as I touch the ground it's not possible to move.

Added a missile (Left Mouse Button), an explosion, and the start of taking damage when one of the the blobs touches you. Nothing really interesting, but for those who absolutely feel like trying it out Build 2 (2.7 MB)
